David Cameron is on Parkinson tonight – I’ll open a thread once the programme starts at 10.45pm on ITV1. The Tory leader appears alongside Lewis Hamilton, James Blunt and Ian McKellen but doesn’t get a mention in the advance billing for the programme.

On the programme David Cameron talks about the time he met Kate Moss…

"I went to a charitable dinner the other night and Philip Green came up to me and said, ‘Would you like to meet Kate Moss?’ So I said, ‘Well, of course I’d like to meet Kate Moss.’ I went over to her table and on the way over I thought, what on earth am I going to say?

"And I remembered she actually has a house in my constituency and we’d had these terrible floods in West Oxfordshire and so I said, ‘Very nice to meet you, very sorry about the flooding in your house. I know your local pub has been flooded, I’ve been to see the publican and I know you like to go to the pub and so I know it’s going to re-open in six months.’

"So I went on like this, twittering on, and she turned around and said, ‘God, you sound like a really useful guy, can I have your phone number?’"

Mr Cameron went on: "I went back to my table and said, ‘The good news is, I met Kate Moss and she wanted my telephone number. The bad news is, I think she thinks I’m something to do with drainage.’"

Mr Cameron is also asked if his relationship with Gordon Brown resembles that of Hamilton V Alonso. He discusses his privileged upbringing and the challenges of raising his own disabled son, Ivan.
